I cant wait to get my first pair of rays!!!! the 2 pups are gonna be housed, well were gonna be housed in my 240gal but kinda afraid of my 20incher TSN getting ahold of them so, dunno i might be a little too worried??? So i picked up a premolded pond its 60x36x18.5 its only temp for maybe half a yr or so then ill have my 800gal indoor pond ready for them and should be big enough to house together with the TSN!!!!!!!!!
